But having a more hardened browser literally does nothing to protect you. If your bank's website is hacked because of a third party API, the most well-hardened browser (as the commenter that I replied to describes) in the world will happily allow all of your money to be stolen. A slow-but-secure JS engine does not protect you from JS that's doing things it's allowed to do.

Oh, oh, oh. I thought this was the thread where we turned javascript off or used adblock or some such. Yeah, secure vs insecure jit engine isn't going to help here.
